How about showing PostRank only on unread items?

I'm new to AideRSS. Correct me if I'm wrong: it now shows PR on every single item, read or unread. I wish it could show PR only on unread ones. In this way, It not only saves bandwidth and other related resources, but also makes things clearer. Because most people do not care about what the PR is with an item already read. Or, at least give me an option for this.

Thanks for listening. AideRSS does help.
